JOHN DOLPHISE OLIGNY, OF ST. HENRY, CANADA.

ARTIFICIAL FUEL.

SPECIFICATION forming part of Letters Patent No. 570,495, dated November 3, 1896.

Application filed April 3, 1896. fierial No. 586,096. (No specimens.)

To all whom it 712/5074 concern:

Be it known that I, JOHN DOLPHISE OLIGNY, a citizen of the Dominion of Canada, residing at St. Henry, in the county of l'loohelaga and Province of Quebec, Canada, have invented certain new and useful Improvements in Artificial Fuel; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to artificial fuel; and it consists in the composition of matter hereinafter fully described and claimed.

This composition comprises about five tons of combustible absorbent material, such as sawdust or peat, twenty-five gallons of gasoil, so venty-five gallons of tar-oil, fiftypounds of common soda, five pounds of cream of tartar, and two hundred and fifty pounds of pulverized lime.

The gas-oil and tar-oil are different qualities of crude petroleum.

The gas-oil used in making this fuel is an intermediate distillate which comes between refined oil and tar. It is too heavy for making refined oil, and it is called gas-oil because it is frequently used in place of coal in the manufacture of illuminating-gas. The tar-oil is the liquid residue left in the still after the refined oil and the gas-oil have been removed.

The gas and tar oils, soda, and cream of tartar are first mixed together and placed in a tank. Air is then forced through the mixture by means of an air-compressor of approved construction for about four hours, so that the oils may become thoroughly aerated and charged with oxygen. The sawdust or peat and the lime are then added, and the mixture is thoroughly incorporated and is pressed into blocks of convenient size and shape for use as fuel.

lVhat I claim is-- l. A new composition of matter, comprised of gas-oil, tar-oil, soda, cream of tartar, combustible absorbent material, and lime, substantially as and in the proportions hereinbefore set forth. a

2. The method of making artificial fuel, which consists in first forcing air through a mixture of gas-oil, tar-oil, soda, and cream of tartar, and then incorporating the aerated mixture with combustible absorbent material mixed with lime, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
